Blocked a frame with origin "mysite" from accessing a frame with origin "facebook". The frame being accessed set "document.domain" to "facebook", but the frame requesting access did not. Both must set "document.domain" to the same value to allow access. contentscript_siteoverlay_bin.js:78
Blocked a frame with origin "mysite" from accessing a frame with origin "youtube". Protocols, domains, and ports must match. contentscript_siteoverlay_bin.js:78
Blocked a frame with origin "mysite" from accessing a frame with origin "googleads". Protocols, domains, and ports must match. contentscript_siteoverlay_bin.js:78

阻止了来源为“mysite”的框架访问来源为“facebook”的框架。被访问的框架将“document.domain”设置为“facebook”，但请求访问的框架没有。两者都必须将“document.domain”设置为相同的值以允许访问。contentscript_siteoverlay_bin.js:78
阻止了来源为“mysite”的框架访问来源为“youtube”的框架。协议、域和端口必须匹配。contentscript_siteoverlay_bin.js:78
阻止了来源为“mysite”的框架访问来源为“googleads”的框架。协议、域和端口必须匹配。contentscript_siteoverlay_bin.js:78
阻止了来源为“mysite”的框架访问来源为“facebook”的框架。请求访问的帧具有“http”协议，被访问的帧具有“https”协议。协议必须匹配。

a secure site can not communicate with a not-secure site
安全站点无法与不安全站点通信
just make everything secure to make things easier. Sites like Facebook are going to require it anyways.
只是让一切安全，让事情变得更容易。无论如何，像 Facebook 这样的网站都会需要它。

You cannot access values in the embedded facebook page. That is against the Same Domain Policy. The two sites can communicate using postMessage if you control both sites, but I doubt that you control the facebook part ...
您无法访问嵌入式 Facebook 页面中的值。这违反了相同域策略。如果您控制两个站点，这两个站点可以使用 postMessage 进行通信，但我怀疑您是否控制了 facebook 部分...
